Have you achieved the standard operation of the burst generator test

Have you achieved the standard operation of the burst generator test
Everyone must know how to use the pulse group generator, but I want to say that when we use the pulse group generator for the test, we must be standardized, because the operation principle of the pulse group generator is a relatively complex device. If we do not carry out the standard operation in the test, it is likely to cause line errors and test obstacles. So today, I will tell you about the specifications that the pulse group generator should comply with in the test

First of all, we need to know that the pulse group generator test uses interference to charge the line junction capacitance. When the energy on the junction capacitance accumulates to a certain extent, it may cause line (or even system) errors. Therefore, there is a process of line error, and there is a certain contingency. It cannot be guaranteed that the error will occur at any interval, especially when the test voltage is close to the critical value. For this reason, some product standards stipulate that the test on the power line is conducted between the line and the ground. It is required to conduct three tests on one line under one test voltage polarity, one minute each time, with an interval of one minute: after one polarity is completed, change to another polarity. When one line is finished, change to another line. Of course, pulses can also be injected into two lines, or even several lines at the same time.
